(CI. 24o-78) 4 Claims.
This invention relates-to lighting fixtures and more particularly to ceiling xtures for the interior of railroad vehicles and the like.
One of the objects of this invention is to provide a lighting xture which is light and inexpensive in construction, yet pleasing in appearance, and particularly well adapted for use in railroad cars or the like. Another object is to provide a construction of the above character which is simple in construction, thoroughly practical, and reliable in operation. Another object is to provide a construction of the above character which will illuminate evenly and ellciently the interior of railroad cars or the like. Another object is to provide a construction of the above character which may be readily and inexpensively manufactured. Another object is to provide a construction of the above character which may be installed with a minimum amount of labor and upon which repairs may be made with the greatest ease. Another object is to provide a construction of the above character which can be readily installed in cars of standard construction in units of varying lengths without necessitating material changes in the construction of the lighting fixture. Another object is to provide a construction of the above character which precludes the necessity of wiring the car. Another object is to provide a lighting fixture of the above character which is so constructed that an even amount of light is given olf at all points throughout the length of the lighting ixture. Other ob- .iects will be in part obvious and in part pointed out hereinafter.
The invention accordingly consists in the features of construction, combinations of elements and arrangements of parts as will be exemplied in the structure to be hereinafter described, and the scope of the application of which will be indicated in the following claims.
In the accompanying drawings in which is shown one of the various possible embodiments of this invention,
Figure 1 is a perspective view of the lightingv tain features of this invention, it might here be pointed out that the installation of lighting lixtures which extend throughout the length of a railroad car along the ceiling thereof presents many diilculties. One of these diillculties lies in the fact that the spaces Within which the xtures are to be installed vary in length, depending upon the design of a car, and thus, to obtain a continuous fixture throughout the length of a given space, it is necessary to especially design the fixtures to t the particular space involved. This increases the cost of design and construction. A still further diliculty lies in the fact that the light emitted by continuous lixtures of the above type comes from a series of light-emitting members. As these members are mounted on sockets, and as the light given off at the ends of a tube lamp is less than the amount given olf in the middle, the dilusing members of the xture are unevenly illuminated. This detracts from the appearance of the xture. It is, accordingly, another object of this invention to provide a lighting xture of the above type which overcomes the above-mentioned diiliculties, as well as many others.
Referring lrst to Figure 1, the lighting xture generally indicated at II), is preferably mounted on a ceiling member, such as the clerestory of a railroad car. Generally speaking, this fixture preferably runs throughout the entire length of the clerestory and is characterized by elongated tubular illuminators suspended in alignment therealong to form preferably a continuous lightemitting band throughout the length of the railroad car. In general, the xture comprises an elongated metal trough, generally indicated at l2, which is mounted over and secured to the edges of a longitudinal opening in the clerestory Il (Figure 2). Trough I2 carries a series of plates, one of which is generally indicated at I3 in Figures 1 and 2, which both support the lluorescent tubes of the lxture and serve as reliectors. This trough also carries a sexies of globes I4, I5, and I6, which may be detached therefrom by exing, all as will be fully described hereinafter,
As shown in Figure 2, metal trough I2 may be made in any suitable lengths and may be continuous for the length of the clerestory in which the fixture is to be installed. It includes a pair of sidewalls, generally indicated at Il and I8, which extend downwardly from top wall I9, flange outwardly to form a pair of shoulders 20 and 2|, and thence extend downwardly again. The lower edges of the trough ange outwardly,
downwardly, thence outwardly again, and then they are bent back upon themselves to form iianges 24 and 25 and grooves 22 and 23. Flanges 24 and 25 serve to mount the fixture in the opening formed in the clerestory of the railroad car and may be secured to the edges of this opening in any suitable manner, as diagrammatically indicated in Figure 2.
Referring now to Figures 3 and 4, the lightemitting members are preferably fluorescent tube lamps and each lamp 26 (Figure 4) is mounted upon an individual supporting plate, generally indicated at 21, extending diagonally thereacross. Each plate, such as plate 21, is ilat and includes a center portion 28 and a pair of tongue portions 29 and 30 extending outwardly from opposite sides of the ends thereof. The tube lamps, such as lamp 26, are mounted diagonally across the plates on sockets 3| and 32, which are secured to plate 21 neara the ends of tongues 29 and 30, respectively. The main portion of these sockets and the wiring for them is positioned above the plates (Figure 2) and the lamp is supported below the plates by the lower portions of the sockets which extend through openings 33 and 34 (Figure 4). One of each pair of sockets carries a starter switch 35 which is utilized in the usual manner to place the lamp to which it is connected in operation and which extends downwardly into the space between the tongue portions of adjoining plates, such as switch 36 (Figure 2).
When the plates are in assembled relationship (Figure 3), the tongues at the adjoining ends of the plates extend alongside one another. Thus, the tongues on each plate overlap the adjoining tongues on the adjoining plates. As the lamp sockets and thus the ends of the lamp on each plate are positioned adjacent the ends of the tongues thereof, the ends of the tube lamps are positioned in overlapping relationship with respect to each other (Figure 3). Furthermore, because of the length of the tongues, the supporting plates 21 (Figure 3) may be moved longitudinally with respect to each other to increase or decrease the amount of overlap of the tongues and thus of the lamps. Accordingly, the total length of a series of supporting plates may be varied by moving them toward or away from each other, and thus, a series may be adjusted so that it ts in a given space or length of clerestory without requiring time-consuming and expensive alterations for different lengths encountered in installation.
As best shown in Figure 3, when a series of plates, generally indicated at 21a, 21h, and 21e, are positioned in assembled relationship, spaces remain between the ends of the tongues of each plate and adjoining plates, the size of these openings depending on the length adjustment a particular installation requires. As these plates together with the sidewalls I1 and I8 (Figure 2) of the trough form the reflector of the fixture, these open spaces are preferably covered by plates 35 (Figure 3). These plates are secured to the ends of each tongue by screws 40 and are of sufcient length to blanket the spaces regardless of the lengthwise adjustment of the plates with respect to each other. Thus, these open spaces are at all times covered regardless of the adjustment of the plates and a full reecting surface is provided for the lamps.
To secure the lamp supporting plates 21 to metal trough I2, two series of slots 4I and 42 are provided in the outer edges of the plates and cover members. A series of holes (not shown) are tapped in shoulders 20 and 2| (Figure 2) of trough I2, the distance between the holes being less than the length of the slots 4I and 42. Thus, when the plates are located in the trough with their edges resting against shoulders 20 and 2|, a hole is always available for every slot. Screws 43 (Figure 2) pass through these slots and are threaded into the holes in shoulders 20 and 2|. When the plates are thus secured, they form a passageway 44 (Figure 2) in the trough for the reception of the upper portions of the sockets and the wiring 45.
Globes I4, I5, and I6 are preferably troughshaped and are made of translucent material able to withstand considerable flexing, such as a resilient, translucent plastic. As best seen in Figure 2, a pair of flanges 46 and 41 extend outwardly from the upper edges of the globes. The Width of each globe between these flanges is greater than the distance between grooves 22 and 23, which, as described hereinabove, extend along the lower edges of trough I2. Thus, to mount a globe on the xture, one of the globe ilanges is inserted in one of the grooves, and pressure is applied to the opposite side of the globe. This exes the upper edges of the globe toward each other, and when the globe is properly positioned, the pressure is released, and the other flange is resiliently urged into the'other groove. Thus, the globes are securely mounted upon the trough. However, they may be easily and quickly removed therefrom for cleaning or repairs.
Between each pair of globes a spacer member 48 (Figures 1 and 2) is vertically positioned.
. These members are preferably at, are made of a plastic, and are secured to trough I2 in any suitable manner such as by brackets 49 and bolts 50. These spacer members separate the globes so that, when a globe is flexed as it is being mounted on or removed from the xture, its ends move freely over the ilat surfaces of the spacer members. Thus, these spacer members prevent interference with the flexing action of a globe by the ends of its adjoining globes.
Thus, a xture is provided which may be easily and quickly installed in a clerestory of any length without requiring alteration of any of its lamp-supporting parts. Furthermore, it is so constructed that it evenly illuminates all portions of the railroad car, for the globes provide a continuous band of light throughout its length. Another advantage, which materially aids the attractiveness of the fixture, is achieved by so constructing the xture that tne globes thereof are evenly illuminated throughout the length of the fixture. A still further advantage lies in the fact that the globes are so constructed and mounted that they may be readily removed from or mounted upon-a lighting xture, and thus repairs and cleaning may be easily and quickly accomplished. Thus a practical and eilcient lighting fixture is provided which overcomes the above-mentioned difliculties as well as many others.
As many possible embodiments may be made in the above invention and as many changes may be made in the embodiment above set forth, it is to be understood that all matter hereinbefore set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
